Practice: 578 - Stream Crossing

Scenario: #1 - Culvert Installation, >30 inch diameter

Scenario Description:Install a new culvert greater than 30" in diameter. HDPE and CMP are acceptable materials under this scenario. For culverts less than 30" use Practice Standard 587 Structure for Water Control. Work includes dewatering, site preparation and removing any old crossing, acquiring and installing culvert pipe with gravel bedding and fill (compacted), and building headwalls. If a different travel surface is needed, refer to another appropriate standard for the surfacing. 36 inch Culvert installation with <75 cy of fill needed and < 2 yds rock riprap for headwalls. Pipe is 40 feet long.Use (396) Aquatic Organism Passage instead, when the primary intent is biological concerns, not hydrologic. Use (587) Structure for Water Control instead, for ditch cross culverts and other intermittent flows and culverts less than 30" in diameter.

Before Situation:Water flow could not cross access road or trail without erosion; or access road or trail could not cross channel.

After Situation:Access road and waterflow are able to cross each other in a stable manner.Stream flow is not impeded and a stable base exists for equipment, people and/or animals to cross. Associated practices could be (342) Critical Area Planting, (560) Access Road, (575) Animal Trails and Walkways, (566) Recreational Trails and Walkways, (500) Obstruction Removal, or (584) Channel Stabilization.

Scenario: #12 - Bridge, Light Weight Timber

Scenario Description:Light Weight Timber bridge is constructed of 6" x 10" timbers side by side bolted together by ASTM A307 Bolts to provide a deck for animal traffic and light weight equipment such as ATV's. Deck is fabricated into 3 - 4'x20' panels which are moved into position by an excavator. Bridge is placed accross a narrow incised stream where installing a ford or other type of crossing is not practical. Bridge deck is mounted on precast concrete blocks which are buried 1/2 to 3/4 into the ground. Approaches to both ends of the bridge are graded to meet the contour of the existing or proposed animal trail. Bridge opening determined by sizing for storm event dictated in standard. Streambanks and bed at crossing location are generally stable. Work consists of furnishing and installing four precast blocks to mount bridge, furnishing 24 - 6" x 10" timbers and assembling the bridge on site, necessary hardware, and lifting bridge panels into place by hydraulic excavator. Span is less than 14 feet. Bridge is intended for cattle passage and not for heavy weight equpment. Bridge width is 12 feet. Use (396) Aquatic Organism Passage instead, when the primary intent is biological concerns, not hydrologic.

Before Situation:Access to pasture is not possible without causing excessive erosion and other water quality water concerns.

After Situation:Access and waterflow are able to cross each other in a stable manner. Stream flow is not impeded and a stable base exists for light weight equipment, people and/or animals to cross. Associated practices could be (342) Critical Area Planting, (560) Access Road, (575) Animal Trails and Walkways, (566) Recreational Trails and Walkways, (500) Obstruction Removal, or (584) Channel Stabilization.
